摘要

本文对圆柱形和环形超导线圈中存储的磁能进行了比较分析。为了公平比较，在分析和数值模拟中，相似的尺寸用于两个线圈(直径和横截面)。使用有限元COMSOL Multiphysics®软件进行了数值模拟。通过分析和数值模拟，环形线圈的能量存储比等效圆柱线圈的能量存储高65%和57%。结果表明，与圆柱和环形磁线圈的数值模拟相比，解析模型的误差分别为21%和3.7%。

Comparative numerical analysis of the stored magnetic energy in cylindrical and toroidal superconducting magnetic coils

In this paper a comparative analysis of the stored magnetic energy in cylindrical and toroidal superconducting magnetic coils is performed. For a fair comparison, similar dimensions are used for both coils (diameter and cross section), in analytical and numerical modeling. The numerical modeling has been performed using the finite element COMSOL Multiphysics® software. The energy stored in a toroidal coil is compared with an equivalent cylindrical coil and is shown to be higher with 65% and 57% using the analytical and numerical modeling, respectively. Also, the results have highlighted an error of 21 % and 3.7% for the analytical modeling compared to the numerical modeling in case of cylindrical and toroidal magnetic coils, respectively.
